I hate smart televisions, and since I live in Korea I doubt such a refrigerator would really matter to me personally, but when you think about it, it seems like one logical step for them to take now that things can be delivered in as little as one hour. Potentially your refrigerator could order and accept orders autonomously once you have a robot capable of answering the door. Of course there are massive privacy implications here too. Do you want Amazon to know about your food allergies? The type of food you eat? That sort of information seems really appealing to third-parties.
